Devonian were gas chromatographically analysed for low molecular weight aromatic hydrocarbons. Aromatic hydrocarbons range from 0.5 to 45.6 per cent with benzene, toluene and the xylenes averaging 80 per cent of the aromatic content. Trimethylbenzenes (of which 1,2,4-trimethylbenzene is the most ...
For a pulse of 1.18 cm3 of trimethylbenzene isomers and 40 g of molecular sieves 13X, the effects of pressure, temperature, and flow rate on separation effectiveness were examined. The results indicated that the most appropriate operating conditions for obtaining a higher recovery of each isomer ...

Process for making a non-pourable ultra-low molecular weight ethylene polymer composition and blends thereof. Such polymer compositions tend to have longer lamella and a greater degree of crystalline organization than corresponding higher molecular weight materials at an equivalent density. Inventors...
Wet weight per plant was 1.10 g on average. Identifications based on retention indices and GC-MS: (1) oxalic acid, allyl hexyl ester; (2) bicyclo[3.1.0]hex-2-ene, 2-methyl-5-(1-methylethyl)-; (3) benzene, 1,2,3-trimethyl-; (4) 6-methyl heptanoate; (5) butyl pyruvate; (...
luminescence spectroscopy to understand the detailed extraction and complexation behavior of europium(III) using a renowned phosphonium based functionalized ionic liquid, trihexyltetradecylphoshonium bis(2,4,4-trimethylpentyl)phosphinate ([P66614][C16H34PO2]) dissolved in 1,3-diisopropyl benzene (DIPB)...
The present invention relates to an ultrahigh-molecular-weight ethylene copolymer powder having an intrinsic viscosity (η) of 10 dl/g to 34 dl/g, obtainable by copolymerizing ethylene and at least one olefin selected from the group consisting of α-olefins having 3 to 20 carbon atoms, cyclic...

There is disclosed a solid composition of polyglycidyl compounds having a molecular weight of less than 1500, which composition consists of one or more than one solid polyglycidyl compound and altoget
of each dyad or regioregularity, whose values ranged from 38% to 95% with this molecule, were analysed using common NMR spectroscopic data. Additionally, the synthesis of a new cationic polyelectrolyte, poly{1,4-(2/3-aminobenzene)-co-alt-2,7-[9,9´-bis(6’’-N,N,N-trimethylammonium...
